Electrode Mounting for Potentiostatic Anodic Polarization Studies

Functionalized Anodic Aluminum Oxide Membrane–Electrode System for Enzyme Immobilization

A nanoporous membrane system with directed flow carrying reagents to sequentially attached enzymes to mimic nature’s enzyme complex system was demonstrated. Genetically modified glycosylation enzyme, OleD Loki variant, was immobilized onto nanometer-scale electrodes at the pore entrances/exits of anodic aluminum oxide membranes through His6-tag affinity binding. The enzyme activity was assessed...

Prediction of the Current Density at an Electrode at Which Multiple Electrode Reactions Occur under Potentiostatic Control

Compensating for Electrode Polarization in Dielectric Spectroscopy Studies of Colloidal Suspensions: Theoretical Assessment of Existing Methods

Dielectric spectroscopy can be used to determine the dipole moment of colloidal particles from which important interfacial electrokinetic properties, for instance their zeta potential, can be deduced. Unfortunately, dielectric spectroscopy measurements are hampered by electrode polarization (EP). In this article, we review several procedures to compensate for this effect. First EP in electrolyt...

Anodic Voltammetric determination of gemifloxacin using screen-printed carbon electrode

The electrochemical oxidation behavior and voltammetric assay of gemifloxacin were investigated using differential-pulse and cyclic voltammetry on a screen-printed carbon electrode. The effects of pH, scan rates, and concentration of the drug on the anodic peak current were studied. Voltammograms of gemifloxacin in Tris-HCl buffer (pH 7.0) exhibited a well-defined single oxidation peak. A diffe...

Improved Nerve Cuff Electrode Recordings by Sub-threshold Anodic Currents

Computer simulatioins indicate that the propagation velocity of action potentials in a length o f a nerve axon can be decreased by subthreshold extracellular anodic currents. This phenomenon can be used to increase the amplitude of whole nerve recordings madie with a short cuff electrode with circumferencial metal bands, since larger propagation delays between the bands result in larger recorde...
